摘要：

This paper studies coupled Fokas-Lenells equation that governs the dynamics of dispersive optical solitons in birefringent fibers. Lie symmetry analysis retrieved several solutions along with conservation laws. The conserved quantities are finally computed using the bright soliton solution reported earlier.
